Abstract: The present disclosure provides a method and device for dynamic recognition of emotion based on facial muscle movement monitoring, including: obtaining muscle movement data on one side and continuous frame images on the other side; obtaining multiple emotional states related to emotions, associating each emotional state with its corresponding continuous frame images, associating each emotional state with the muscle movement data corresponding to the continuous frame images at the same location and at the same time, to form a training set, building an emotion recognition model; inputting the muscle movement data and continuous frame images obtained in real time into the emotion recognition model to obtain a corresponding emotional state. This method builds an emotion recognition model through muscle movement data and continuous frame image, and uses motion data to make up for the parts of small action images that cannot be collected, thereby obtaining accurate emotion detection results.

Abstract: Systems and methods of a novel self-serve, customer driven data platform that can automatically unify and structure the data that comes from different sources, in order to provide well defined data for any federated learning task. This platform solves a critical problem for federated learning which usually requires multiple different data sources jointly learning one model. In the real-world scenario, the assumption that most existing federated learning frameworks have, that different data owners follow the same rule or structure to save the data, usually does not hold. Our data platform is the one of the novel and heuristic ways to solve this practical problem and makes larger scale and automated industrial level federated learning achievable.
